DATE 2008-10
The signal transmission rate of personal computer peripheral devices and digital devices as represented by USB2.0 devices is being
increased year by year, and countermeasures against ESD are critical in high-frequency bands. We have developed Type KVA
Surge Absorber to protect the circuits of various electronic devices sensitive to ESD.
Since the surge absorber has a low capacitance of 0.08 pF, it is applicable to high-speed signal lines.
The ecology design of Type KVA is environmentally friendly because of Lead-free and Halogen-free.

Surge Absorber absorbs and suppresses static electricity.
1. Circuit Design
Type KVA Surge Absorber is a part for protection from static
electricity and cannot be used for protection from lightning surge.
Before using Type KVA Surge Absorber, sufficiently examine its
electrical characteristics and the circuit conditions to be
mounted.
(1) Type KVA should always be operated below the rated
voltage.
(2) Use Type KVA under the condition of category temperature.
Type KVA should be selected by determining the operating
conditions that will occur after final assembly, or estimating
potential abnormalities through cycle testing.
2. Assembly and Mounting
During the entire assembly process, observe Type KVA body
temperature and the heating time specified in the performance
table.
In addition, observe the following items :
(1) Mounting and adjusting with soldering irons are not
recommendable since temperature and time control is
difficult.
In case of emergency for using soldering irons, be sure to
observe the conditions specified in the performance table.
(2) Type KVA body should not have direct contact with a
soldering iron.
(3) Once Type KVA mounted on the board, they should never
be remounted on boards or substrates.
(4) During mounting, be careful not to apply any excessive
mechanical stresses to Type KVA.
3. Solvents
For cleaning of Type KVA, immersion in isopropyl alcohol for 90
seconds (at 20 ~ 30°C liquid temp.) will not be damaged.
If organic solvents (Pine AlphaTM, Techno CareTM, Clean
ThroughTM, etc.) will be applied to Type KVA, be sure to
preliminarily check that the solvent will not damage the Type
KVA.
4. Caution During Usage
Type KVA should never be touched in use.
5. Environmental Conditions
(1) Type KVA should not be operated in acid, alkali, or active
gas atmosphere.
(2) Type KVA should not be vibrated, shocked, or pressed
excessively.
(3) Type KVA should not be operated in a flammable or
explosive atmosphere.
(4) After mounting Type KVA on a board, covering Fuses with
resin may affect to the electric characteristics of Type KVA.
Please be sure to evaluate it in advance.
6. Emergency
In case of fire, smoking, or offensive odor during operation,
please cut off the power in the circuit or pull the plug out.
7. Storage
(1) Type KVA should be stored at room temperature (-10°C ~
+40°C) without direct sunlight. Direct sunlight may cause
decolorization and deformation of the exterior and taping.
Also, there is a fear that solderability will be remarkably
lower in high humidity.
(2) If the products are stored for an extended period of time,
please contact Matsuo Sales Department for
recommendation. The longer storage term causes
packages and tapings to worsen. If the products are stored
for longer term, please contact Matsuo Sales Department
for advice.
(3) The products in taping, package, or box should not be
given any kind of physical pressure. Deformation of taping
or package may affect automatic mounting.
8. Disposal
When Type KVA are disposed of as waste or “scrap”, they
should be treated as “industrial waste”. Type KVA contain
various kinds of metals and resins.
9. Samples
Type KVA received as samples should not be used in any
products or devices in the market. Samples are provided for a
particular purpose such as configuration, confirmation of
electrical characteristics, etc.
